Specific embodiment

With reference to the accompanying drawing and specific embodiment is further elaborated the utility model.

As shown in Figures 1 to 5, the puncture needle of the anti-dropout of the present embodiment, comprising: pedestal 1, syringe needle 2, anti-dropout screw thread, One end of the syringe needle 2 connects pedestal 1, and the other end is puncture tip, is provided with anti-dropout screw thread on 2 end of syringe needle or pedestal 1； When the syringe needle 2 is inserted into infusion bag 6, anti-dropout is threaded into the sack of the infusion bag 6 as will be described, and realization prevents described The function that puncture needle falls off.

Wherein, the anti-dropout screw thread can be the end thread with the one of syringe needle 2, for syringe needle 2 connect on pedestal 1 with base 1 material of seat is identical, integrated screw thread or the screw thread being separately provided different from syringe needle and pedestal with pedestal 1.Anti-dropout screw thread is set Meter can be selected according to actual production mode or usage mode, and the utility model is not to the specific circle number of screw thread, setting Position carries out considered critical, and all similar designs theories are all within the scope of protection of this application.

In order to which the puncture needle to above-mentioned anti-dropout carries out apparent explanation, come below with reference to a specific embodiment It is illustrated, however, it should be noted that the embodiment merely to the utility model is better described, is not constituted to this reality It is improperly limited with novel.

Fig. 1 is the structural schematic diagram of the puncture needle of the anti-dropout of the utility model first embodiment.As shown in Figure 1, first Screw thread 3 is set on the outside of the slot of pedestal 1, and when medical staff uses the puncture needle, syringe needle 2 can be inserted into the bag of infusion bag Mouthful, and pedestal 1 is screwed, slot is screwed into the sack of infusion bag, prevents puncture needle from falling off.

Fig. 2 is the application schematic diagram of the puncture needle of the anti-dropout of one specific embodiment of the utility model.As shown in Fig. 2, base The bottom of seat 1 connects catheter 4, for conveying the liquid in liquid bag；Wherein, one end of catheter 4 is provided with drain interface 7, The drain interface 7 connects the bottom of the pedestal 1；When in use, syringe needle 2 can be inserted into the bag of infusion bag 6 by medical staff Mouthful, pedestal 1 is then screwed, when the pedestal 1 rotation, the drain interface 7 is not rotated with the pedestal 1, to keep drain Pipe 4 is static.

In the above-described embodiments, being set to first screw thread 3 on the outside of slot is a circle or multi-turn, and a circle screw thread is convenient for Medical staff's operation.

Fig. 3 is the structural schematic diagram of the puncture needle of the anti-dropout of the utility model second embodiment.As shown in connection with fig. 3, if The second screw thread 5 for being placed in the side wall of the syringe needle 2 is multi-turn, is located at 2 lower half portion of syringe needle, the first screw thread 3 is set to outside slot Side；After setting can also make medical staff's insertion needle 2 in this way, carries out screwing fixation, prevent puncture needle from falling off.

Fig. 4 is the structural schematic diagram of the puncture needle of the anti-dropout of the utility model 3rd embodiment.As shown in connection with fig. 4, with Unlike Fig. 3, the second screw thread 5 is laid in whole side walls of syringe needle 2.

Fig. 5 is the structural schematic diagram of the puncture needle of the anti-dropout of the utility model fourth embodiment.As shown in connection with fig. 5, it inserts It can also be not provided with screw thread on the outside of slot, second screw thread 2 only is set in the side wall of syringe needle 2, when also may be implemented using puncture needle Anti-dropout.

The set-up mode of above-mentioned puncture needle can according to need and design is adjusted, and the application is only set out a part of real Mode is applied, so technology as associated class is all within the scope of protection of this application.

The utility model is not limited to above-mentioned optional embodiment, anyone can obtain under the enlightenment of the utility model Other various forms of products, however, making any variation in its shape or structure, all the utility model rights that falls into are wanted The technical solution in confining spectrum is sought, is all fallen within the protection scope of the utility model.
